Deprecate MSN Messenger ports to expire 31 OCT 2013
Microsoft ended the primary MSN service for all countries by 30 APR 2013.
Third party clients still work although they can only communicate with
other such clients. The XMPP protocol service is expected to be shut down
by October 2013 [1] although MSP service may continue into early 2014. [1]
Deprecate all ports that exclusively use MSN protocols and mark the
expiration by the end of October.

At the moment 1385 ports use BUILD_DEPENDS= ${RUN_DEPENDS} and 450
ports use BUILD_DEPENDS:= ${RUN_DEPENDS}. This patch fixes ports that are
currently broken. This is a temporary measure until we organically stop using
:= or someone(s) spend a lot of time changing all the ports over.
Explicit duplication > := > = and this just moves ports one step to the left
